    Abstract: Embodiments of methods for determining a location of a mobile device, a mobile device, and a location beacon system are described. In an embodiment, a method for determining a location of a mobile device involves receiving, at a dual-antenna receiver of the mobile device, a plurality of ultra wide band (UWB) signals from a group of unsynchronized beacons having a quadrilateral formation, at the mobile device, determining angle of arrival (AoA) information from the UWB signals, and at the mobile device, calculating the location of the mobile device based on the AoA information. Other embodiments are also described.

    Abstract: An apparatus includes an antenna that is configured to transmit a radio frequency signal across a transmission media having a channel response impairment. A transmission path includes an encoder circuit that encodes data on a carrier signal; and a pre-equalizer circuit that is configured to pre-distort the encoded data according to equalizer coefficients representing the channel response impairment. A first equalization path includes circuitry that generates the equalizer coefficients based upon transients resulting from a presence change event for the carrier signal. A second equalization path includes circuitry that generates the equalizer coefficients based upon knowledge of encoded data on the carrier signal. Selection circuitry selects between the first equalization path and the second equalization path.

    Abstract: In one embodiment, an apparatus is provided that includes a first circuit configured and arranged to provide a modulated carrier signal in response to a signal provided from the antenna. The modulated carrier signal conveys data using peaks or amplitudes of the carrier signal. A second circuit is configured to rectify the modulated carrier signal and integrate the rectified signal in response to a first clock signal. A third circuit is coupled to an output of the second circuit and is configured to sample the integrated signal values and provide therefrom a sample-based approximation of the modulated carrier signal.
